You can’t learn to speak — to say things — without learning to say something. And you can’t learn to program — to talk to a computer — without learning to program something. Learning to program therefore not only provides the opportunity to learn to instruct a computer, but is also an opportunity to learn about everything else in the world.
When learning something new, by coming to understand its fundamental elements or building blocks you’ll not only learn more, and more exciting things, but have a greater amount of expressive power with that knowledge. It is essential, however, that the process of learning those detailed fundamentals takes place with the big picture always in mind, and in sight. Literally as well: appropriate visuals greatly improve the learning process by serving as memory and reasoning aids.
